下田 鷹臣

Also known as the Gentleman Spirit (謎の紳士 Nazo no Shinshi, lit. "Mysterious Gentleman"), is a ghost trapped inside Heavenly Host Elementary School. He resides in one of the stalls in the boys' lavatory on the third floor. 

Takaomi is, for the most part, a gentleman whose courteous behavior doesn't betray his refined appearance. He is also somewhat eccentric, spouting phrases such as, "I love you!" in English. He claims to have been very protective of his subordinates in life, which carries over in the afterlife as he shows genuine concern for the unfortunate humans trapped inside Heavenly Host. The only occasion in which he ever breaks this personality is whenever someone opens the door to his residential toilet stall without his permission, to which he furiously roars at the person to shut the door. However, he claims this is so because he is actually easily frightened by his surroundings, and only feels secure inside the stall.
